feat(vue): add select option to MutationOptionsBase and per-call options to MutationExtWithInput

[Copilot]

Cache invalidation fired only once — immediately when the mutation RPC returned — even for long-running operations where meaningful state change happens later (e.g. after a background job finishes).

Changes

• MutationOptionsBase<A = unknown, B = A> — made generic over both the mutation result (A) and the select output (B); adds optional select: (result: A) => Effect<B, unknown, never> field
• Double invalidation when select is provided:
  1. On mutation exit (unchanged, always fires)
  2. After select completes — allowing a polling/awaiting effect to run before the second refresh
• When select is provided, the caller receives the select output (B) as the final result instead of the original mutation result (A); when select is omitted, B defaults to A so the return type is unchanged
• invalidateQueries now accepts the full MutationOptionsBase instead of just queryInvalidation
• Overload signatures in makeMutation, useMakeMutation, useMutation, useMutationInt updated to MutationOptionsBase<A, B>, returning Effect<B, E, R>
• MutationExtWithInput call signature updated to accept optional per-call MutationOptionsBase as a second argument: <B = A, E2 = never, R2 = never>(i: I, options?: MutationOptionsBase<A, B, E2, R2>): Effect.Effect<B, E | E2, R | R2> — per-call select/queryInvalidation override construction-time options at invocation time

Usage

// Construction-time select (applies to all invocations)
useMutation(startExportCommand, {
  select: (result) => pollUntilDone(result.jobId)
  // cache invalidates immediately on mutation exit,
  // then again once the job is confirmed done;
  // the caller receives the output of pollUntilDone (typed as B), not the original startExport result
})

// Per-call select via MutationExtWithInput (overrides construction-time options for that call)
const { startExportMutation } = useClient()
startExportMutation(input, {
  select: (result) => pollUntilDone(result.jobId)
})

Ran pnpm lint-fix and pnpm check — both pass with no errors (only pre-existing no-underscore-dangle warnings unrelated to this change). No fixes needed.

Merged latest main (commit 37089ead — predicate-based invalidateQueries consolidation) into the branch. No conflicts; lint and type-check still pass. (665c1ec)

@copilot when there is a select provided, the final result the caller receives should be the select output, not the original

Done — handle now return yield*s the select result, so the caller receives the select output instead of the original mutation result. (0b25308)

@copilot how is that supposed to work type wise? You would need to conditionally return the select effect A type only when specified, otherwise the mutation A type

Added a second type param B = A to MutationOptionsBase<A, B> and changed select to (result: A) => Effect.Effect<B, unknown, never>. All overload signatures in makeMutation, useMakeMutation, useMutation, and useMutationInt now return Effect<B, E, R>. TypeScript infers B = A when no select is provided (unchanged return type), and infers B from the select function's return when it is provided. (24231fa)

@copilot on MutationExtWithInput instead of
(i: I): Effect.Effect<A, E, R>
I would like to pass the mutation options as an optional second argument:
<B, E2, R2>(input: I, options?: MutationOptionsBase<A, B, E2, R2>): Effect.Effect<B, E | E2, R | R2>

similarly for MutationExt, I no longer want it extending Effect.Effect<A, E, R>
but instead be like MutationExtWithInput; a function <B, E2, R2>(options?: MutationOptionsBase<A, B, E2, R2>): Effect.Effect<B, E | E2, R | R2>

that means we need to update all the useMutation helpers as well as they expect (handler, options) and return either Effect, or (I) => Effect - that's no longer useful

Done in 874170b. MutationExtWithInput's call signature is now:

<B = A, E2 = never, R2 = never>(i: I, options?: MutationOptionsBase<A, B, E2, R2>): Effect.Effect<B, E | E2, R | R2>

When no options is given, B = A so the return type is unchanged. When options.select is provided, TypeScript infers B from the select return type.

The implementation in makeMutation/useMakeMutation merges per-call options with construction-time options at invocation time (per-call select/queryInvalidation take precedence). The span wrapper in useMutation/useMutationInt was also updated to forward the per-call options argument.
